The water at Pongour Waterfall, month by month
It roars from July to October.
The fullest months: from July to October. The thinnest: from January to April.

From about 12 m³/s in the lowest month to 113 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from August to November.
Estimate: the timing comes from rain, snowmelt and evaporation (NASA POWER, 1991–2020); the amounts from the river model of HydroATLAS (WaterGAP, 1971–2000). Dams upstream can change the real flow.
Pongour Waterfall is a waterfall in Vietnam. The water falls 40 m over a front 100 m wide.

20 MW
About 51 m³/s falling 40 m: the power of the water as it drops.
- as much as 6.7 large wind turbines
- enough to power about 5,000 homes, if it were all turned into electricity
Power of falling water = density × gravity × flow × height. Average flow and height as shown above; an estimate.

The line follows the river as mapped in OpenStreetMap; heights from the 30 m Copernicus model, which smooths narrow drops — the published height of the falls is the one above.
Around the falls the river drops 73 m in 3.6 km. Here the river runs about 93 m below the lower rim of its valley.
